menses.

To all whom itmay concern."

Be it known that l, F'rrz GENT, a citizen of the ,United States, and a resident of Mahwah, in the county of Bergen and State of New Jersey',have made and invented certain new and useful Improvements in Reinforcing-Backs for Brake- Shoes, of which the following is a specificw tion.

This invention relates to reinforcing backs for brake shoes, andconcerns in particular thattype of back whereinthe looped lug portion is provided with reinforcing and bracing means, so as to prevent the spreading and opening up thereof.

An object of the present invention is to means for bracing this the same in an' economical manner. In bracing the lug portion and reinforcing back, it has, heretofore,'been the practice to provide a separate tie-plate which extends beneath the lug of the back and is secured by V rivets or other suitable means to the sides of thelug. This provision of a separate tieplate, in addition to requiring considerably more material than ordinarily embodied in a brake shoe back, also requires that the tieplate be secured and anchored to the back at both of its ends.

A material saving of metal is ed'ected in the present invention by forming the he- "plate from a portion of the back itself,

the removal of which tie plate'defines an opening, through which the body metal of the shoe flows, and which materially aids in the anchorage thereof. Tn addition, but one joint is required for the securement and anchoir-age of the tie-plate to the back.

A further object is to provide av reinforcing back with alooped. lug, and with a he plate formed integral therewith, the tieplate being; bent beneath the opening, and up and'around the remote portion of the back, so that it is rigidly and permanently anchored thereto, and does not depend upon the cast metal of the body of the shoe for its securement. 7

Other objects and advantages will appear as the description proceeds, wherein it is to be understood, that changes in the precise embodiment of my invention, can be made.

within the scope of what is claimed, without departing from the spirit thereof.

j The preferred embodiment of my invent on is disclosed'in the accompanying draw- Figure l s from which my improved reinforcing back is formed; Fig. 2 is a view in longitudinal vertical section of the reinforcing back embodying the characteristic features of my invention," Fig. 3 is a tragmental view inperspect ve of the same, andon an enlarged scale; Fig. t is a new 1n transverse vertical section of a brake shoe with my novel reinforcing back embodied therein; andFig.

5 is a view inside section of a somewhat slightly modified form of reinforcing back,

the modification residing in the securement of the free end of the tie-plate to the back.

Referring specifically to the; several views,

the blanln'illustrated in Fig. l, is formed from an oblong plate 5, the central and lugforming portion 6 of which, is provided with the spaced and symmetrically arranged.

openings 8. To one side of the lug portion 6, is provided the U-shaped slot 10, the same being so located as to define a tongue 11, the free portion of which, is located remote from the lug portion .6 of the blank. Upon the opposite side if the lug portion, with regard to the tongue 11, is provided the opening 9, which; in connection with the opening defined" by the removal of the tongue 11, as hereinafter'described, provided the usual'openings, into which the metal of the body of the shoe may flow for its secure anchorage.

The blank, as above outlined, is looped or bridged at its central portion to form the outwardly looped and integral lug 7, the

openings 8 in which, are adapted to receive the usual shoe attaching key. The tongue 11 is bent downwardly beneath the plate 5, and across the open lug 7, and, as thus lo-v cated, forms an integral tie-plate 12, the

one extremity of which is formed integral 1 withthe back adjacent theone side of the lug and the remote extremity 13 of which is bent up through the openingil, and aroundthe edge thereof, so as to become securely and permanently anchored thereto, the S9,".

curement and anchorage of which does not depend upon the cast metal of the body of the shoe, althou h it may be, to some extent,

supplemented t ereby. The over lapping end 13 of the tie-plate is removed a suficient distance from the lug, so as to not interfere with the attachment of the shoe to the break head.

- The reinforcing back, as thus constituted, is placed within the mold and the wearing metal of the body is cast thereon. The body metal of the shoelying directly ,beneaththe open lug 7 is reinforced by'the-tie-pl'ate 12,

secured and anchored thereto by the rivet 14, this rivet being formed from the cast metal of the. body of the shoe flowing up through the alined openings 15, with which the tie-plate and the reinforcing back are provided.

- What I claim is 1. A reinforcing back for brake shoes with an open looped 111g, and a tie-plate formed'integral with said back, extending across said lug and permanently anchored to said back. v

2. A reinforcing back for brake shoes with a looped lug, and a tie-plate formed integral with said back, and extending beneath said looped lug, the free extremity of said tie-plate Zak:I tie-plate permanently secured to said ac t 3. 'A reinforcing back for brake shoes with anoutwardly formed lug, and a tieplate connected to and formed integral with said back, adjacent one side of said lug,

being bent beneath and extending across to the opposite side of said lug andpermanently anchored thereto.

4. A reinforcing back for brake shoes formed with an outwardly looped lug, a tie- Z'plate formed integral with said back, and

projecting across said lug. with the free eX- tremity thereof bent into engagement and interlocking with said back.

5. A brake shoe comprising a reinforcing back-with an outwardly looped lug, a tieplate formed integral with said back and projecting across said lug and anchored to the remote side thereof, and a body anchored to said reinforcing back and. tiepla'te, with the metal thereof extending into the opening defined by the formation of said tie-plate.
